9. Frigidaire FAD954DWD – Budget Pick

Check Price at Amazon


Specifications:


  • Area Coverage: 1,800 sq. ft.
  • Max Water Removal (Saturation) PPD: 95 pints/day
  • Max Water Removal (AHAM Standard): N/A
  • Process Air: 259 CFM
  • Power: 7.3 amps
  • Filter Type: Washable Filter
  • Drain Hose Length: Not included
  • Power Cord Length: 6 feet

  • Housing: Durable plastic
  • Operating Temperature: Down to 41°F
  • Auto-Restart:
  • Auto-Defrost:
  • Auto-Diagnosis:
  • Timer:
  • Wheels:
  • Warranty: 1-year full/5-year sealed system


We recommend this option for small business places like a coffee shop or a workshop. Ideally, the space shouldn’t overcome 1,800 square feet, so the unit can perform its best and remove up to 95 pints of moisture per day. It is well-built and provided with a strong fan that will produce a maximum airflow of 259 CFM, drawing the humid air through the dehumidifier and releasing it dry and safe to breathe. The permanent washable filter keeps bacteria away from the water recipient and cleans the air, improving its quality. Moreover, you can adjust speed, and we suggest to use high speed at first, until the humidity is brought within normal parameters, and medium or low speed to maintain it this way.

Concerning the design, although it isn’t a heavy-duty model, it is strong enough to resist basement conditions. The plastic casing is durable and provides good sealing for the interior components. It is provided with built-in side handles and comes with 4 strong casters for easy transportation around the place, which could include carrying it up and down the stairs. Moreover, it is provided with a long 6-feet power cord that allows you to place it far from the wall to reduce vibrations and, thus, the noise. The only thing this model lacks is a pump that would have made water drainage easier. It does offer a continuous drain option, but it depends on gravity to evacuate the water, therefore if you decide to use it, you will need to direct the water into a floor drain or to place the dehumidifier on a higher level if you are going to drain it into a sink or another recipient.

Nevertheless, we must agree that the price is very attractive, especially when we consider the 1-year warranty for the full unit or the 5-year warranty for the sealed system. They are offered by one of the most renowned brands in the industry, so you can rest assured that they will be carried through. But, on the other hand, we must mention the running costs, which are not as low as you would have expected. Although it is Energy Star certified, this model consumes a maximum of 870 watts, which will certainly show on your electricity bill, if you decide to run it continuously. Some customers, however, reported that if you run it on the lowest speed and remember to set the timer and give it a break once every 24 hours, you can lower the costs to a decent value.

In case you don’t opt for continuous drainage, it offers a generous front bucket with a splash guard that can be easily removed. But keep in mind that the bucket has a smaller capacity than this model’s dehumidification rate, therefore you will need to empty it several times a day. It will let you know that it is full through an indicator light on the digital control panel, and the unit will automatically shut down if you forget to empty it. Apart from that, if the temperature in the basement or other space where you decide to use it goes extremely low, reaching a minimum value of 41 degrees, the auto-defrost function will kick in and periodically warm the coils so they don’t freeze.

What we like:
  • Quick moisture removal due to the highly-performant fan
  • Easy set up in less than 15 minutes
  • Continuous drain option
  • Auto-defrost function prevents its internal components from freezing
  • Casters and side handles make it easy to transport
  • Timer allows for run-time customization and helps save energy
What we dislike:

✖ Doesn’t feature a pump

✖ The humidistat is not very accurate

✖ High power consumption rate

Verdict

Although the energy consumption rate is high, we must acknowledge that this is one of the most powerful dehumidifiers for small spaces we have tested. It quickly removes dampness from the air and makes room for freshness. Furthermore, it is easy to install and control, as it comes with a user-friendly digital panel that offers instant access to all the settings, functions, and signals.


8. Aprilaire 1852 Pro – Best for Ducting

Check Price at Amazon


Specifications:


  • Area Coverage: 5,200 sq. ft.
  • Max Water Removal (Saturation) PPD: 95 pints/day
  • Max Water Removal (AHAM Standard): N/A
  • Process Air: 265 CFM
  • Power: 8 amps
  • Filter Type: Washable MERV 8
  • Drain Hose Length: 5 feet
  • Power Cord Length: 8 feet

  • Housing: Scratch- and dent-resistant metal
  • Operating Temperature: Down to 40°F
  • Auto-Restart:
  • Auto-Defrost:
  • Auto-Diagnosis:
  • Timer:
  • Wheels:
  • Warranty: 5-year


It comes with a durable metal case that can resist scratches and dents and includes corrosion-resistant aluminum coils, therefore it is up for many years of use. The practical design allows you to connect it to the HVAC system and provide dehumidification for your entire business place, especially as it can cover large surfaces, measuring up to 5,200 square feet. Nevertheless, you can choose not to duct it, if you need to cover an individual space, as it offers continuous drainage and comes with a 5 feet hose that can be placed in a floor drain to direct the water. Thus, no matter the option you choose, you will never have to deal with water recipients or buckets that usually fill too fast and need to be emptied several times a day.

It features an 8 amperes motor which is the main reason for the excellent 265 CFM airflow. Although the fan is rather noisy when the unit is used on its own, when it is ducted, it produces a noise of only 54 dB, which is a very low level for a commercial unit. Regarding the dehumidification rate, 95 pints per day is a good value, but we must agree that this dehumidifier is not very fast. However, you can increase its performance if you use it in a smaller space or if you buy 2 units for your extra-large business place.

It includes a washable MERV 8 filter, which is very sturdy and effective against impurities and large airborne particles. Proper care and cleaning will extend its life, so you will only have to replace it once a year to maintain the system in good shape. It is provided with casters for easy transportation, but it doesn’t have a handle, so carrying it on the stairs may be difficult. Nevertheless, it requires minimal maintenance, so you can set it and let it run, even if the weather outside is turning cold, as it comes with an auto-defrost function and can stand temperatures down to 40 degrees Fahrenheit. Additionally, it is backed by a very generous warranty that can be used in case of manufacturing flaws or mishaps occurred during normal utilization.

The auto-restart function will prove very useful as well, as it won’t allow for long periods of pause within the dehumidification process. In fact, as soon as the power is back on, after a power outage, the unit will restart its program with the last settings selected by you. Plus, it consumes less energy than the Frigidaire model, with a peak of 638 watts, so running it on longer periods will be less expensive. Nonetheless, it doesn’t feature a timer, so you will need to turn it off manually every time you decide to save some money.

What we like:
  • Very long 5-year warranty
  • Auto-restart function
  • Works in low-temperature conditions
  • Can be integrated into a HVAC system
  • Durable filter needs to be changed only once a year
What we dislike:

✖ It is slow for the recommended area

✖ Doesn’t feature a timer

Verdict

It is easy to install and maintenance is a breeze, this is why it is so popular among customers, who buy it to maintain humidity under control into small to medium places. It can be ducted for whole-building dehumidification or used individually in a basement or a very humid room. Furthermore, it is built of strong materials and the coils have been treated against corrosion, so you have the guarantee that it will last for years of run in harsh conditions.


7. BlueDri BD-76P-RED – Best for the Money

Check Price at Amazon


Specifications:


  • Area Coverage: 600-900 sq. ft.
  • Max Water Removal (Saturation) PPD: 150 pints/day
  • Max Water Removal (AHAM Standard): 76 pints/day
  • Process Air: 235 CFM
  • Power: 7.3 amps
  • Filter Type: Washable air filter
  • Drain Hose Length: 15 feet
  • Power Cord Length: 25 feet

  • Housing: Molded polyethylene
  • Operating Temperature: 33°F – 100°F
  • Auto-Restart:
  • Auto-Defrost:
  • Auto-Diagnosis:
  • Timer:
  • Wheels:
  • Warranty: 1-year/10-year housing


It is a versatile model that can be used in any location, whether we are talking about a construction site where the excessive humidity must be drawn fast, or in a basement that was flooded and needs to dry out for the restoration to begin. The housing is built of molded polyethylene, therefore it offers excellent protection against scratches and bumps, allowing for use in extreme conditions. It is easy to transport as it comes with two semi-pneumatic wheels and a strong rigid handle, so you can move it from one room to another if the whole space has been flooded. Moreover, both the drain hose and the power cord are long, the first measuring 15 feet, and the latter 25 feet, so you will be able to position it properly between the floor drain and power source.

In terms of performance, we must admit that it is one of the most powerful, and, considering the price, it is an excellent long-term investment. First of all, it has an impressive water removal capacity of 150 pints per day in a space measuring up to 900 square feet. It isn’t the best area coverage, but many dehumidifiers promise to cover thousands of square feet and prove to be ineffective. Our tests revealed that, although this unit can perform well in larger spaces, if used in a room under 900 square feet, it is extremely fast and performs as described by the manufacturer. Besides that, it comes with a water pump, which is already an extra, but very useful if you don’t have a floor drain and need to dispose of the water into a sink.

It can work for days in extreme temperature conditions, with values that can range from 33 to 100 degrees Fahrenheit. It features an auto-defrost function and will restart automatically in case of a power outage. The digital panel is placed on the top, allowing for easy access to settings. It includes an LCD screen as well that will show humidity level and count the hours of continuous use.

The stackable design will help you save space in your storage if you decide to buy more than one unit. The power cord can be rolled and hanged at the back of the unit so it doesn’t get tangled. Apart from that, this reliable unit is backed by a 1-year warranty for the system and up to 10 years for the housing.

What we like:
  • Heavy-duty housing
  • Easy to transport due to the large wheels and rigid handle
  • Comes with a water pump
  • Auto-restart function
  • Stuckable design
What we dislike:

✖ Someone complained that the instructions are difficult to understand

Verdict

All in all, it comes at an excellent price and can be put to work in a wide variety of spaces, so you will make a good investment no matter if you are planning to use it on a construction site or to restore your whole house after an unfortunate flood. Moreover, it is strongly built and covered by a long warranty, so you can rest assured that it will serve you well for many years to come.

With a dehumidification rate of 150 pints, it will quickly remove moisture from warehouses, hospitals, restaurants, supermarkets, computer labs, art galleries, and many others. The 7.3 amperes motor can work day and night without a pause to restore places that have been flooded. The polyethylene housing is very resistant and will stand harsh environmental conditions, including high humidity and low temperatures. Moreover, it is difficult to scratch and was designed to resist bumps and dents, so the system will be well protected over the years.

Nevertheless, the best thing at this unit is the portable design that allows you to easily transport it from one place to another or carry it up and down the stairs. It isn’t light, with a weight of over 80 pounds, but it is equipped with large semi-pneumatic wheels that roll smoothly on any surface. The rigid handle is an excellent addition as well as it offers stability and eases to burden, especially when stairs are involved. Furthermore, it was designed to be stacked upon another unit, so if you need 2 of them for a very large space, you will be able to save floor space in your storage by storing them vertically.

The convenience is increased by the extra-long 40 feet drain hose and 25 feet power cord, which allow for the unit to be placed in an optimal position around the space. It includes a water pump that will make continuous drainage easier, allowing you to direct the water either into a floor drain or a sink. Apart from this, it can be used to assist in water evaporation when connected to a vent hose, as it comes with a built-in attachment ring.

The digital control panel is provided with an LCD screen that displays the relative humidity and hours of continuous work. The dehumidifier can be easily controlled with the help of only 3 buttons: on/off button, purge – which activates the pump, and auto-defrost which can be used during the cold season and will activate the hot gas bypass system to prevent the internal coils from freezing. Regarding power consumption, it is an energy-efficient unit and comes with a timer that can be set to shut down the operations after one hour, 2 hours, and up to 24 hours, so it is easy to customize the run time and energy costs.

What we dislike:

✖ Some customers complained that customer service is not very responsive

Verdict

It is covered by a 1-year warranty during which the manufacturer promises to replace any broken part or the whole unit if you discover a manufacturing flaw. The system is well-built and the housing is made of strong polyethylene that will last harsh work conditions. Apart from that, it is suitable for large spaces where it can be easily transported around as it comes with sturdy wheels and a reliable handle.

Getting rid of moisture after a flood can be a difficult task, especially if the space you are trying to dry is large. You will need a powerful unit that can work continuously for days in high-humidity conditions without being affected by low temperatures or rust. Our tests revealed this model from AlorAir to be the best in these situations, as it has a very sturdy construction and comes with a pump to help drain the collected water. The coils are epoxy-coated, therefore they will preserve their heat transfer ability for longer.

The housing is made of rotomolded polyethylene, which is practically indestructible, very resistant against bumps and water. The system is completely sealed with rubber bands and can be sunken into the water without getting wrecked or developing rust and corrosion. Therefore, you don’t have to wait until the water is removed completely to start the restoration process. The fan is actioned by a 5.4 amperes motor that generates a high airflow of 210 CFM. Thus, it can cover extended spaces, measuring up to 2,300 square feet. The dehumidification rate is impressive, with a maximum of 190 pints of water that can be removed daily, or up to 85 pints according to AHAM standards.

It comes with a 15 feet hose and 19.6 drain pipe, allowing you to direct the water into a floor drain or a sink, as it features a solid pump that will raise it to a height of 14.7 feet. The power cord is long as well, measuring 19.6 feet, therefore you can place it far from the wall for increased efficiency. Regarding its size, we have noticed that it is more compact than most models in its class and more lightweight, therefore it is easier to lift, especially as it comes with 2 rugged handles. Nevertheless, the burden is still serious, and it could use a set of wheels for easier transportation.

The digital panel is straightforward, with only 4 buttons that allow for easy setup and function selection. It is provided with an LCD screen that displays temperature and humidity at both outlet and inlet. It includes an auto-restart function with memory and an auto-defrost function that will kick in when the temperatures reach extremely low values. In this case it will activate the hot gas defrosting system and keep the coils from freezing. The system can work at temperatures between 33 and 105 degrees Fahrenheit. Plus, the warranty is very generous, as the manufacturer offers 5 full years for repairs.

What we like:
  • Epoxy-coated coils last longer and maintain their performance
  • Waterproof construction
  • Strong airflow can cover large spaces
  • Very high dehumidification rate
  • High-quality water pump
What we dislike:

✖ Lacks wheels

Verdict

With a power consumption rate of 640 watts, we can call it energy-efficient, especially as it comes with an integrated timer that allows you to customize run time. The sealed system and rotomolded construction make it suitable for water damage restoration in large spaces like industrial institutions, warehouses, shops or garages. Moreover, as it comes with a pump, water drainage is easy to manage, and you won’t have to worry if you don’t have a floor drain available.

  • Max Water Removal (AHAM Standard): 76 pints/day
  • Process Air: 235 CFM

  • Auto-Diagnosis:
  • Timer:
  • Wheels:
  • Warranty: 1-year


In spaces that have been flooded, the humidity level is so high that only a commercial unit with a strong pump can resolve it. You cannot rely on the traditional continuous drainage as it can be too slow in evacuating the water. Not to mention that a dehumidifier that uses a bucket is completely useless in this case. What you need is a strong motor and a pump that can raise the water into a sink or out of the window. If this is what you are looking for, this model from XPOWER is your best option, as it comes with a long 20 feet drain hose and a purge function that will help you drain the water fast.

With a dehumidification capacity of 125 pints per day and an airflow of 235 CFM, it will do its best in a medium-size space of up to 1,500 square feet. Thus, it is the right option for basements, attics, shops, or construction sites, at which it was already tested and performed exceptionally. The housing is made of rotomolded polyethylene, which is the standard in the industry for its strength against humidity and temperature variations and its resistance to bumps and scratches. Two strong semi-pneumatic wheels were added to absorb the shocks and smoothly roll the unit on any terrain. A rugged handle will help you move it without bending and will prove very efficient if you need to carry it on the stairs.

The advanced electronic panel allows you to set the humidity standard between 26% and 90%, and the unit will work to bring it to the selected value. You can follow its progress on the LCD screen, which, apart from the relative humidity value, will display total working hours as well. It doesn’t feature an auto-restart function, which would have been very useful, but the auto-defrost mode is present and will periodically heat the coils to maintain them in good shape if the temperature drops down to 41 degrees or even lower, as it can operate within a range of 33 and 100 degrees Fahrenheit.

It comes with a washable high airflow filter that will strain impurities and remove bacteria and mold spores, creating a safer environment. The filer is easy to remove for periodical cleaning, which should be performed at least 2 times a month if the dehumidifier is used continuously. The 25 feet cord allows you to find a good spot for it in the room from which you can evacuate the water efficiently. Moreover, the whole system is backed by a good 1-year warranty that can be used in case of manufacturing flows or other mishaps that are specified in the agreement.

What we like:
  • Strong pump connects to a 20 feet drain hose and can pump the water to a considerable height
  • Can operate in extreme temperature conditions
  • Easy to set up as it requires minimal assembly
  • Auto-defrost function
  • Resistant housing and coils
What we dislike:

✖ No auto-restart function

✖ No timer

Verdict

It is equipped with a reliable pump that will automatically direct water into the drain-source selected by you, so you can leave it unsupervised and only inspect once in a while if the humidity has reached the level selected by you. The purge button will help you evacuate the water manually if you wish to get it out of the unit faster before powering it off. Therefore, we can agree that it is very convenient to run, and an excellent choice for water damage restoration and mold and mildew control, as long as it is used in the appropriate space.


3. Dri-EAZ F413 Revolution – Editor’s Choice

Check Price at Amazon


Specifications:


  • Area Coverage: 7,000 sq. ft.
  • Max Water Removal (Saturation) PPD: 136 pints/day
  • Max Water Removal (AHAM Standard): 80 pints/day
  • Process Air: 180 CFM
  • Power: 6.2 amps
  • Filter Type: 3M HAF
  • Drain Hose Length: 25 feet
  • Power Cord Length: 40 feet

  • Housing: Rotomolded polyethylene
  • Operating Temperature: 33°F – 100°F
  • Auto-Restart:
  • Auto-Defrost:
  • Auto-Diagnosis: N/A
  • Timer:
  • Wheels:
  • Warranty: Limited lifetime on body, 6-year on compressor & coils, 1-year parts & labor


This brand is renowned for its high-quality dehumidification solutions which include both commercial units and products for residential use. Although their prices are higher than the average, we must admit that thy deliver superior quality and excellent performance rates, so investing in a model like F413 Revolution will only bring you benefits in the long run. Everything is well-thought and carefully engineered for long-time use, starting with the rotomolded polyethylene housing that encases the rust-resistant coils and ending with the premium functions that allow for easy customization.

It was designed to provide fast dehumidification for extra-large spaces with a surface of up to 7,000 square feet or a volume of 15,000 cubic feet, therefore it is an excellent choice for warehouses, professional garages, offices or whole houses. It can draw up to 136 pints of moisture per day, as it uses a high-quality fan to generate an airflow of 180 CFM. The air is drawn through a 3M HAF filter that includes an anti-microbial agent, therefore it is specially designed to remove the bacteria and mold spores that tend to grow in humid places. The air is cleaned and released into the room only when it is safe to breathe. Nevertheless, this is not a permanent filter, so you will have to replace it every 4 to 5 months to maintain the system’s performance.

Another convenient feature is the built-in pump. Most dehumidifiers offer a continuous drain option, which means that the water can go directly into a floor drain through a hose. Nevertheless, these systems rely on gravity for this job, so, unless you manage to place the unit on a level above the level of your sink or window, you won’t be able to drain the water into them. In this case, the pump replaces gravity and even works against it by sending the water up through a long 25 feet drain hose to the draining option selected by you. Furthermore, the power cord measures 40 feet, which means that you can place it near the window or sink even if the outlet is situated across the room. Worthy of mentioning as well, it can be connected to a duct if you choose to purchase the optional kit.

The digital panel is user-friendly, with well-labeled buttons and an LCD screen that helps you easily set the desired humidity. The value can range between 40% and 90%, and we recommend to run it at 50% for mold and mildew control and set it to 40% if you are using it for water damage restoration. Apart from the digital humidistat that constantly monitors the humidity in the room, it comes with three smart functions, namely a timer – for a customized run, auto-restart – with memory function that will power it back on in case of a power outage, and auto-defrost – very useful in cold areas. Moreover, the warranty is very attractive, as the manufacturer offers 1 year for parts and labor, 6 years for the internal coils and compressor, and excellent limited lifetime coverage for the housing.

What we like:
  • Very effective in large spaces
  • Built-in pump makes water drainage easier
  • 3M HAF filter is very effective in removing bacteria and mold spores
  • Can be connected to a HVAC system
  • Strong construction
  • Long warranty
What we dislike:

✖ Pretty expensive

Verdict

If you are looking for quality, you should take a good look at this model, which was certainly made to last. Everything, starting from the housing to the internal coils and pump mechanism, was carefully crafted to deliver the best results. Multiple functions were included for easy customization. Plus, it is very fast, even when it is used in large spaces like commercial settings or crawl spaces, so you will get rid of the unpleasant humidity effects in no time.


2. COLZER CFT4.0D – Best for Large Spaces

Check Price at Amazon


Specifications:


  • Area Coverage: 8,000 sq. ft.
  • Max Water Removal (Saturation) PPD: 232 pints/day
  • Max Water Removal (AHAM Standard): 110 pints/day
  • Process Air: 353 CFM
  • Power: 15 amps
  • Filter Type: Washable high-dense filter
  • Drain Hose Length: 6.56 feet
  • Power Cord Length: 5.9 feet

  • Housing: Scratch- and dent-resistant metal
  • Operating Temperature: 41℉ -95℉
  • Auto-Restart:
  • Auto-Defrost:
  • Auto-Diagnosis:
  • Timer:
  • Wheels:
  • Warranty: 2-year


While all the models included in our top are highly performant and able to operate in large spaces, this unit has the advantage of offering a complex digital panel with multiple smart functions that make it easier to customize for specific operating conditions. It is provided with a digital humidistat, which is very accurate in tracking humidity values in the room. The two arrow buttons that are situated next to the large LCD screen allow you to set the desired level and the system will run continuously until it is reached. It includes a temperature sensor as well, which can be used in conjunction with the auto-defrost function to prevent the internal coils from freezing when the temperatures drop down to 41 degrees Fahrenheit. Additionally, a timer is available so you can easily control run time, and you will probably use this function a lot to save energy, as it isn’t the most energy-efficient unit, with a maximum power consumption rate of 1,400 watts.

Nevertheless, if we consider its ability to cover spaces as large as 8,000 square feet, the power consumption rate can seem decent, as, usually, for this surface are used two units instead of one. The dehumidification rate is outstanding, reaching up to 232 pints per day or 110 pints according to AHAM standards, so we have ranked it among the fastest models. The high-quality fan can deliver a huge airflow of up to 353 CFM, and the air will be drawn through a high-density filter, designed to remove dust and other particles that can end up inside the system and gradually reduce its performance. The filter is washable, so you won’t need to replace it too often.

The housing is built of strong metal that stands bents and scratches. It is provided with 2 semi-pneumatic wheels that ease transportation from one work site to another and a large rugged handle for easy manipulation that attenuates a bit the discomfort of its bulky construction. These features, along with the auto-restart function allow you to set it running in any place and forget about it, as it is not prone to rust and corrosion and can restart its system if a power outage occurs.

The only defect we could find was the lack of a water pump. It does offer continuous drainage, but based on gravity, so it requires a floor drain. The 6.56 feet hose and 5.9 feet power cord are pretty short as well, when compared with the other models. However, it does make up through easy maintenance, as it features an error-detection function that signals malfunctions and allows you to obtain troubleshooting tips through error codes. Plus, the whole system is covered by a pretty good 2-year warranty, which is offered by a reliable manufacturer.

What we like:
  • Multiple smart functions
  • Portable design
  • Suitable for large job places
  • Fast dehumidification in large areas
  • User-friendly digital panel

When it comes to producing commercial dehumidifiers, Dri-Eaz surely knows its business. This is one of their most performant models, designed to ensure optimal water removal for large spaces like restaurants, hotels, construction sites, or warehouses. In this direction, it was equipped with a strong housing and advanced dehumidification technology that allow it to run in low-grain environments. Furthermore, it uses smart sensors to measure temperature and humidity and can adjust its operations to reach optimal parameters fast and efficiently.

Indestructible Construction

It is a commercial unit, therefore it should be able to run for extended periods in spaces with harsh environmental conditions. Moreover, as you will invest good money into it, it should last for many years, and preserve its performance. Our analysis revealed that it is suitable for the job, and this is easy to see if you look at the following features:

  • Rotomolded polyethylene housing – is resistant to dings and dents and won’t get damaged if exposed to high humidity
  • Heavy-duty hose and power cord – the first one measures 25 feet and the second 40 feet, being suitable for use in large spaces
  • Performant 3M HAF filter – is anti-microbial treated and will fight mold and mildew spores and bacteria
  • Strong semi-pneumatic wheels and handle – make it easy to transport from one job site to another, even if stairs need to be climbed

Although it is bulky and rather heavy, at 121 pounds, with the ergonomic handle, it is easy to maneuver. Plus, if you purchase 2 units, they can be stacked one on top of the other to reduce the space they take on the floor when stored. To provide this option, the handle easily folds down. Another convenient feature is the built-in storage space for the cord and the hose that will help you keep them untangled and safe while not in use.

Fast Moisture Removal

Many customers choose it for water damage restorations, as it can provide quick dehumidification and work continuously without overheating or losing power. Plus, it comes with a high-quality pump, which provides efficient drainage by lifting the water and allowing evacuation into a sink or out the window. Its popularity is increased by the following specifications:

  • Extra-large area coverage – can provide moisture removal for up to 26,000 cubic feet, being a perfect choice for construction sites or whole buildings
  • Outstanding water removal capacity – draws up to 235 pints of moisture per day
  • Crossflow technology – ensures optimal dehumidification even if you have to deal with a low-grain environment
  • Powerful fan – produces an excellent 325 CFM airflow, which reduces water removal time

It can operate at temperatures between 33 and 100 degrees Fahrenheit and can adjust fan speed according to the room size and humidity level. Furthermore, the pump bassinet is very generous, so it can handle the excess of water produced by a defrost in case a power outage occurs. Thus, you can rest assured that all its work won’t be wasted and the humidity won’t be raised again by accidental spills.

Smart Functions

Now, that we have analyzed its construction and capacities, it’s time to take a look at its design. Is the control panel easy to reach and operate? It is. It features 4 buttons and an LCD screen that allow you to set the desired functions, like, for example, the humidity level it should reach. Nevertheless, what’s truly impressive is the multitude of smart functions:

  • Auto-defrost – it activates when the temperatures get extremely low and protects the internal coils against cold and freezing
  • Auto-diagnosis – generates error codes that can be used for easy troubleshooting
  • Auto-restart – in case a power outage occurs, it memorizes the last settings and restarts the unit when the power is back on
  • Timer – helps customize run time and reduce energy costs
  • Digital humidistat and thermostat – analyze humidity and temperature on the premises and allow the dehumidifier to adjust its functions accordingly

Apart from all that, you can select the language, as it offers information in English, French, German, and Spanish. For industrial applications, it includes a wireless function that allows it to connect with a special monitoring system (sold separately) that will help you track site conditions.

Excellent Warranty

The housing is backed by a limited lifetime warranty, and you will probably never have to use it, as it is one of the most solid on the market. On the other hand, if something should happen with the compressor or the coils, it is good to know that they are covered for up to 6 years, which is a very generous offer. Moreover, you get 1 year for parts and labor, and the guarantee that the manufacturer will stand behind their offerings.

What we like:
  • Excellent area coverage and dehumidification rate
  • Easy to customize due to the multiple smart functions
  • Sturdy construction
  • Built-in water pump
  • Large pump basinet prevents accidental spills
  • Multilingual control panel
What we dislike:

✖ Expensive

Verdict

This unit is the best you can get at the moment in terms of power, reliability, and convenience. Although it is more expensive than all the models in our top, it surely deserves all the money, especially as it was built to last tens of years of use. It is smart and can run independently, so you can place it at the job site and forget about it. Plus, you can use it to track the environmental conditions from distance, as it has wireless capabilities.
